Summary - Steps in TEM Specimens Preparation by "Lift-out" Method
 
Animation of Lift-Out Steps
The "lift-out" technique has numerous qualities that make it attractive to industry requiring TEM analysis. The total fabrication time for a site specific TEM specimen by this method is on the order of hours. For traditional FIB TEM specimens, the time is much longer. Of course the speed of fabrication is strongly dependent on material composition, and the geometry of the bulk sample; however, due to the fact that large amounts of ion milling time are eliminated using the lift-out method, it will always be a more rapid means of getting a TEM specimen from a bulk substrate. The final size of the electron transparent cross-section varies, but can be as large as 150 square microns to as small as 45 microns squared. For semiconductor clients, it also means that a TEM specimen can be manufactured from a specific area while leaving the rest of the die intact, which has advantages for failure analysis or design debugging.
